BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a gun and more particularly, to a gun attachment mounting structure, which uses retaining members with springy clamping arms and swivel locking control member to quickly and detachably lock a gun attachment-carrying base member to the gun body of a gun.

2. Description of the Related Art

A gun may be equipped with a sight to assist the user aim the eye at the target. Various optical sights exist, such as laser sight, infrared sight, and night-vision sight. However, different types of guns have a different size of gun body. Conventional optical sights are respectively design for use with a particular gun. For making different sizes of optical sights, different molds must be used. In consequence, the molding cost is relatively increased. Further, conventional optical sights or gun attachments commonly use a single side lock design. After installation, the attached optical sight or gun attachment may be forced out of position by an external force or upon an accidental impact. In this case, the user must correct the positioning of the optical sight or gun attachment again.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1˜4, a gun attachment mounting structure in accordance with the present invention is shown comprised of a base member 1, a plurality of retaining members 2, a plurality of swivel locking control members 3, and a gun body 4.

The base member 1 has a longitudinal coupling groove 11 disposed at one side, namely, a platform 12 disposed at the other side, namely, the top side opposite to the bottom side, a plurality of locating holes 111 and through holes 112 respectively extending from the coupling groove 11 to the outside of the base member 1, a transverse locating block 113 extending across the longitudinal coupling groove 11, and a plurality of locating blocks 13 protruded from one lateral side corresponding to the through holes 112.

The retaining members 2 are made out of an elastic material, each having two springy clamping arms 21.

The swivel locking control members 3 each have a bottom block 31, a camshaft 32 protruded from one side of the bottom block 31, an angled locking block 33 extending from the periphery of the camshaft 32, a mounting rod 34 axially extending from one end of the camshaft 32 opposite to the base block 31, and a handle 35 affixed to the mounting rod 34 with a pin 36 for rotating the respective swivel locking control member 3 relative to the base member 1. Further, a return spring 331 is coupled between the angled locking block 33 and the base member 1.

The gun body 4 comprises a top coupling bar 41. The top coupling bar 41 has a plurality of transverse grooves 42 and transverse tongues 43 alternatively arranged in parallel along the length of the top wall thereof.

The retaining members 2 are respectively mounted in the locating holes 111 of the base member 1 to suspend the respective clamping arms 21 in the coupling grooves 11 at two sides. The swivel locking control members 3 are respectively pivoted to the locating blocks 13 of the base member 1 to insert the respective angled locking blocks 33 into the through holes 112 of the base member 1. By means of the respective handle 35, the user can bias the camshaft 32 of each swivel locking control member 3, moving the respective angled locking block 33 in and out of the respective through hole 112. The coupling groove 11 of the base member 1 is adapted to secure the top coupling bar 41 of the gun body 4. When the top coupling bar 41 is attached to the coupling groove 11 of the base member 1, the clamping arms 21 of the retaining members 2 are respectively clamped on two opposite lateral sidewalls of the top coupling bar 41 of the gun body 4, and the transverse locating block 113 is engaged into one transverse groove 42 of the top coupling bar 41, and thereafter the swivel locking control members 3 are respectively biased to force the respective angled locking blocks 33 out of the respective through hole 112 and stopped against the top coupling bar 41, locking the top coupling bar 41 to the base member 1.

The coupling groove 11 of the base member 1 can be made having a U-shaped or I-shaped groove, a dovetail groove, or any of a variety of other configurations. The top coupling bar 41 is configured to fit the coupling groove 11. Further, pins, screws, or other equivalent members may be used to substitute for the swivel locking control members 3 for locking the base member 1 and the top coupling bar 41 together.

Referring to FIGS. 5˜8, the base member 1 is a single size design. The size of the top coupling bar 41 is determined subject to the type and size of the gun body 4 of the (toy or real) gun. By means of the clamping arms 21 of the retaining members 2 and the swivel design of the swivel locking control members 3, the base member 1 can be locked to any of a series of sizes of top coupling bar 41 that is receivable to the coupling groove 11 of the base member 1. Further, the return springs 331 hold the respective angled locking blocks 33 in the locking position. Further, a laser sight, infrared sight, night-vision sight, or any of a variety of other gun attachments may be carried on the platform 12 of the base member 1. FIG. 8 shows an application example of the present invention, in which a night-vision sight 5 is mounted on the platform 12 of the base member 1.

In general, the gun attachment mounting structure of the present invention has the following features and advantages:

1. After the coupling groove 11 of the base member 1 is coupled to the top coupling bar 41 of the gun body 4, the transverse locating block 113 of the base member 1 is engaged into one groove 42 of the top coupling bar 41 to stop the base member 1 from horizontal displacement in longitudinal direction relative to the top coupling bar 41, and the clamping arms 21 of the retaining members 2 are clamped on the two opposite lateral sides of the base member 1 to stop the base member 1 from horizontal displacement in transverse direction relative to the top coupling bar 41, and the angled locking blocks 33 are stopped against the top coupling bar 41 to stop the base member 1 from vertical displacement relative to the top coupling bar 41, and therefore the base member 1 is firmly locked to the top coupling bar 41.

2. The clamping arms 21 of the retaining members 2 are elastically movable in the respective locating holes 111 of the base member 11, and the angled locking blocks 33 are movable in the respective through holes 112 of the base member 11, and therefore the clamping arms 21 and the angled locking blocks 33 can lock the base member 1 to a different size of top coupling block 41.

A prototype of gun attachment mounting structure has been constructed with the features of FIGS. 1˜8. The gun attachment mounting structure functions smoothly to provide all of the features disclosed earlier.
